Oil Free Screw Compressors Compared to Poor Lubrication Choice

Just any oil will not do for lubrication. Aerzen has decades of experience to back the assertion that using the wrong oil is responsible for 72% of bearing-related problems, whether the oil is contaminated, has aged rapidly, or was not designed to lubricate high-speed machines.

For the best lifetime of a machine, the lubricant used must be specifically designed for high mechanical load, variations in pressure, elevated temperatures, and exposure to oxygen and moisture within the device. The lubricant film will remain intact in thickness if the right type of lubricant is used, preventing the blower from breaking down too early in its lifecycle.

Well-Oiled is Half-Done

With Aerzen Original rotary lobe blower lubricant oil, it is possible to lubricate Aerzen high-performance blowers under all kinds of conditions. These consist of the most advanced oils, carefully selected, and tested by Aerzen through millions of testing cycles to make sure they function well throughout tens of thousands of operating machine hours, with high reliability.

They are guaranteed to have a high stability to temperature, to resist oxidation, behave consistently in the presence of varying medium viscosity or temperature, and pour well at low temperatures. They will also make sure the machine is well-lubricated at all phases of its operation, keeping the blowers and compressors running for a longer time. The Aerzen Original rotary lobe blower lubricant oil contains additives selected to resist corrosion and prevent aging of the oil and the blowers.

Lubrication should be tailored to the operating requirement of the specific equipment, which is made easier by Aerzen’s range of special lubricants as shown in the chart below. These include lubricants compatible with use in the food industry or miscible with other lubricants. Delta Lube 06 does not have to be changed after 500 Oh, while the oil change interval can be extended up to 16000 Oh. Aerzen lubricants are shipped within 24 hours of the order.
